加筋土挡墙动力特性有限元分析

Power Character Element Analysis of Reinforced Soil Retaining Wall

采用分离式有限元模式,建立了由土体单元、接触单元、面板单元和加筋材单元组合的加筋土挡墙有限元模型,并对加筋土挡墙进行了动力有限元分析.结果表明,有限元计算值与试验值相吻合,证明该方法正确有效,由此在工程设计中可以通过针对加筋土挡墙的动力程序R-D,预测挡墙的动力反应.

The power element model was made by the combination of the divorce type and element, soul unit, contact unit board and reinforced group and reinforced retaining wall. And analysis of element was conducted by the reinforced soil retaining wall. The result showed that the counting value of the element and the value of trial constitute the same result. It is proved that the trial design is correct. In the design of the abovementioned project, the motive power order R-D could be obtained by the reinforced soil retaining wall and pre-measure the motive reaction of retaining soil wall.
